Sanctuary will be directed by Apollo 18 helmer Gonzalo Lopez-Gallego and produced by Atlas Independent, the company said today. Written by Ryne Douglas Pearson, the horror pic follows three documentarians who travel to South America to investigate a town that mysteriously disappeared from the map. The trio is led to the ultimate enigma: an immense concrete structure located in the middle of the missing town, with no entrances or exits. Highland Film Group is handling worldwide sales and will introduce the title next month at EFM in Berlin. It marks the latest tie-up between Atlas Independent and Lopez-Gallego, following December 2013’s Open Grave starring Sharlto Copley and The Man On Carrion Road, which was announced at the last Cannes Film Festival and begins production in April. Atlas Independent is currently in post William Monahan’s Mojave.
